8 Best Plus-Size Shapewear 2026, Tested by a Size-16 Woman

What we love: I was genuinely surprised by this Spanx mid-thigh bodysuit. The fabric is smooth, light, and silky—not what I usually expect from plus-size shapewear, which can feel thick and overly compressive. It was relatively easy to get on, but still delivered real shaping and support without rolling or bunching. The open-bust silhouette is the standout: It gives you near full-body smoothing while letting you wear your own bra. That’s especially helpful if built-in bras don’t work for your cup size or you’re dressing for a lower neckline.

Best High-Waisted Brief: Shapellx AirSlim Butt-Lifting Panty

What we love: These butt-lifting panties made me feel so snatched (and I don’t use that term lightly). When I saw myself in the mirror, I did a double take. The mesh along the sides and fully mesh back adds breathability, so they don’t feel overheated. They fit more like a boyshort than a true brief, hitting lower on my thighs—but unless you’re wearing something that shows your entire thigh, they work well as an underlayer. And if you don’t always want to wear a thong, it’s nice to have a brief option. The lift is subtle but noticeable, adding a bit of enhancement without much effort. They’re a little too thick under jeans, but looked great under a fitted skirt or slip dress. It took some effort to get them on—they’re quite compressive—but they felt worth it once in place.
